What's New in Universal Zoom

3.0

July 25, 2026

Version 3.0 is our biggest expansion of the Physics part of the app yet. • A whole new kind of object — point particles like quarks, leptons and bosons. Having no measurable size, they stay put as you zoom instead of growing or shrinking. • 39 objects added or significantly improved — point particles, plus more atomic nuclei and atoms, and a handful of larger objects too. • Particle physics is a tricky topic, so we added 5 short articles that explain it in a simple, easy-to-follow way — with many more articles to come. • We improved the information for many objects, refreshed the images for several of them, and polished translations and voice-over pronunciation. • We fine-tuned the soundtrack volume based on your feedback. Thank you for your continued feedback — it truly helps make Universal Zoom better with every update!

Important Research for Post Solar Scale Development

New objects of the upcoming update and what are they? What shall you add after Solar Scale?

Can ya add more? (And some object subtitle suggestions)

Can you add some things like:
- Sombrero Galaxy (a flat galaxy)
- Apple (one of the most well-known fruits)
- Banana
- Planet X (a hypothetical planet in the outskirts of our solar system) *can also be called Planet 9

Other dwarf planets:
- Orcus (nicknamed the “Anti-Pluto”
- Eris (the most massive but second largest dwarf planet)
- Haumea (one of the most odd dwarf planets)
- Makemake (used to be called “Easter Bunny”)
- Gonggong (used to be called “Snow White”)
- Sedna (one of the farthest dwarf planets)
- Quaoar (has a ring system and one moon)

Your app is really good nonetheless!

Sorry I had to edit again:
There’s something in space that’s located 14 million light years away called Cloud 9. Astronomers think it’s a failed galaxy. It’s pinkish-purple in colour and mostly made of gas and dark matter. It is estimated to be about 4,900 light years across.
